Right - would be easy enough to add but in the current version,
all widgets in a panel are tracked so sliders will slide and
switch buttons will switch. Perfectly reasonable RFE.
FYI - if you want to do your own enhancements,
the source code is in /usr/src/Performer/src/lib/libpfutil/gui.c.

There is no such specific routine.
You are probably drawing the message in the overlay planes via
drawmode(OVERDRAW)?
You can clear the overlay planes to remove all messages, and
you can set viewport or scrmask to clear a portion of the screen.
You can also redraw the text with color(0) - the transparent color
in the overlay planes. This might be the easiest way to clear a
single message in a block of other text.
FYI - It is a very expensive operation to switch drawmode() so anything
that needs to be frequently updated you should do at the end of drawing
and just draw it un-zbuffered.
